ADVERTISING, EDUCATIONAL OR AMUSEMENT DEVICE R THE LIKE Application led January 2, 1931. Serial No. 506,233.

This invention is a method and means for conveying information or a message to a reader in a striking and unusual way, so that an idea, impression or selling point is brought to the readers attention to cause it to stand out in a clear-cutmanner.

More specifically, the invention consists in a method and means which produces a primary effect or impression on the reader` or 1a user, and which also produces a distinct and secondary impression or efl'ect, which may be in more or less sharp contrast to, or a development or modification of the first effeet or impression. The first and second impressions cooperate to create in the mind ot' the user a particular point, idea or message. If the point it is desired to bring out is by way of coiitrast, the contrast may be one of time, place, financial condition, persons, things, climate, etc., according to the particular subject matter. The idea can be carried along by producinlglr additional contrasts, developments or modifications as manyY times as desired.

.-'ecordinn' to this invention, there are provided a single sheet, or two or more. sheets having symbols or indicia thereon, designed to convey certain ideas. Some, or even all of thel sheets may be transparent. 'lhe entire sheet may be transparent, or only parts of it. mayY be trzlnslucent, as by providingr it with translucent panels or transparent inserts. Supposinpr the first sheet is transparent and it with its symbol or symbols is superposed on the following sheet with its symbols. it will be apparent that all the symbols onthe first sheet are visible while at least some, of' the symbols on the second sheet are. visible at the same time. This concur- 40 rent or simultaneous viewing of symbols on both sheets produces a denite impression on the user or reader, due to the composite effeet of the symbols on the first sheet plus whatever symbols on the second sheet are visible through the first sheet. Now when the first sheet is lifted all the symbols on the second sheet become visible, and these symbols are so chosen as to briner out some definite point, which preferably by contrast of time, place, financial condition, environment., change of scene, et'c., with respect to the first impression, roduces a second or supplemental impression which emphasizes the point that it is desired to bring out. In all of these eases, it should be especially noted, part of the message or effect would be definitely lost if the symbols were all on a singrle sheet, or on two opaque sheets. In other words, these represent more than a ln'ealc-upfor division of data on several 60 sheets for convenient reference; they represent a dimensional quality, color, atmosphere or cont-rast, eta-any of which qualities is sometimes more important to the advertiser, magazine publisher, and others, than are the exact phrasing of the words and the exact drawing of the picture.

Home, or even all, of the symbols on the first.- sheet may be placed with respect to the symbols on the second sheet, so as to conceal some ofthe symbols on the second sheet. Such concealment in particular instances is necessary, since the element of suspense or sharp contrast might be lost if all the symbols on the second sheet were visible when the first sheet was superposed on it.

To take a simple illustration, suppose the first sheet contained the Word Business and lshowed a business man in his ofiice working; under high pressure, while the second sheet had the words and Bermuda and showed a picture of thel same business man reclining in tropical sunlight on a palm fringed beach in Bermuda. The words and Bermuda on the second sheet would be visible through the first sheet when the first sheet is superposed on the second sheet but the beach scene would be directly underneath the office scene so that When the two are superposed the beach scene would be concealed. A user, therefore, in viewing the two sheets sees a tired business man in his office, and sees the word and Bermuda appearing through the first sheet. The com- :5 posite effect produced on the reader is to raise in his mind an inquiry as to what Bermuda has to do with a business man, and so the readers curiosity is aroused, and he lifts the transparent sheet and sees the reader is looking at the second sheet superposed on the third, he will see some of the symbols or indicia on the third sheet, his curiosity will be aroused and he will lift the second sheet and read the indicia on the third sheet and so on with any desired number of sheets. The successive veffects produced, through the` el'ements of surprise, contrast of time, place, climate, etc., can readily be arranged or designed to bring out a particularpoint according to the subject matter involved.

While the invention can be carried out with the use of two or more sheets having indicia printed only on one side, it is desirable as a matter of economy to use the reverse side of each sheetv for conveying additional information or message pertaining to the subject matter of those particular sheets. This additional matter, if printed on the reverse side of a transparent sheet could be, and preferably is, screened from the observer when he is looking at the first sheet, by having a portion of the surface printed in opaque ink, or embossed, or screened by pasting on a panel of paper or the like or in any other desired manner thereby lesscning the transparency of the transparent sheet. lf the first sheet is for the most part opaque and provided with transparent windows, this additional matter can readily be applied to the reverse side of such a sheet. The matter that is to be screened is placed or printed on the reverse side directly in back of these opaque or less transparent portions. Or, the symbols on the reverse side ofthe sheet could be printed directly behind some relatively opaque lportion of the obverse side of the transparent sheet, which would act to screen it.

Fig. 5 shows the second sheet of this embodiment;

Fig. 6 shows the reverse side of the first sheet;

Fig. 7 is a view of another embodiment;

Fi 8 is a view of the reverse side of Figz;

Fig. 9 is a view of another embodiment of the invention; and

Figs. 10, 11 and 12 are views showing the first, second and third sheets of this embodiment.

Referring first to Figs. 1, 2 and 3, the invention is here shown in the form of a small leaflet or booklet of three sheets. Numeral 5 indicates the first sheet which may be transparent or semi-transparent. Printed on the upper surface of this sheet 5 is,

for example, a blizzard scene 6, on an opaque panel 7.

The second sheet of the leafiet or booklet, forming a lower indicia-bearing surface, is indicated at 8, sheets 5 and 8 being hinged together along the line 9 as usual. Sheet 8 is transparent orsemitransparent and has f printed on it an opaque panel 10 on which lettering 11 appears. The sheet 8 is also provided with a scene 12 printed on an opaque panel 13, which panel may also show some lettering 14.

Vhen the first sheet 5 is placed over the second sheet 8, the reader gets the effect of Fig. 1, namely a blizzard scene in New York, plus a summer bathing scene showing faintly through the transparent or semi-transparent sheet below the blizzard scene. The main effect produced 1s that of a blizzard, but the bathing scene faintly showing through the sheet, arouses the reader-s curiosity and impels hini to lift sheet 5 and he sees sheet 8, disclosing the bathing scene in full detail, the reader then getting the full effect of the contrast between the blizzard scene in New York and the bathing The two sheets, when viewed as just described, by'virtue of the contrast, produce a general impression of the benefits of going to Florida. This impression is enhanced by the lettering on panel 10 in regard to the round trip fare. The use of the opaque panel 7 effectivel screens the panel 10 until the first sheet 1s lifted. By virtue of the opaque panel 7, the back 5a of the sheet 5 may be provided with lettering 15, which is not visible in Fig. 1, but is, of course, visible in Fig. 2. This lettering 15 may cooperate with the lettering and the scene on sheet 8 to supplement or add to the effect created by sheet 8.

The idea can be carried along further by providing a third sheet 16 which can be opaque or transparent as desired, and which may contain lettering 17 carrying along the general impression of the benefits of a vacation in Florida as originally created by lettering.

reading sheet 8. This-sheet.' 16 may-conf tain vacation scenes 18 and l) also designed to carry along the vacation idea W'heu sheet 8 is viewed as in Fig. 2, the

. reader sees some of the lettering 17 from the third sheet 16, such as The ultra-violet ra s and outdoor sports showing throng from the third sheet. The readers curiosity is instantly aroused and he turns sheet 8 and sees sheet 16 which carries along the general idea of the benefits of a Winter vacation in theSouth. The reverse side 8a of sheet 8 shown in Fig. 3, may have supplementary lettering 2() immediately behind the panel and further lettering 22 behind the panel 13, which lettering would convey further ideas in connection with a vacation in Florida.

It will, of course, be understood that the several sheets may contain only lettering with no scenery, or scenery with no lettering, or a combination of the two, dependent upon the effect it is desired to convey. That is to say the panels 18 or 19 might contain Or, instead of the. lettering 15, or 22, additional scenes could be shown. It Will be noted that certain of the scenes or panels von one sheet will conceal some ot' the symbols or indicia on following sheets. For example, the blizzard scene 6 will screen the lettering on panel 10, and the panel 1() will screen the boating scene 18. Also the bathing scene 12 will screen the golf scene' 19. However, it should be observed that the top sheet does not screen entirely what appears on the second sheet.

It is also within the contemplation of the l*invention. to have certain symbols on` the third slieetiiot only show through the seeond sheet, but also through the first sheet. For example, the wording The ultra-violet rays and out door sports on the third sheet is visible through sheet 8 as shown in Fig. 2, while this same lettering might still be visible when looking at sheet 5.

Color may be ethictively used in bringing out the desired eit'ects. For instance, the bathing scene 12 and letteringlsl about the golden sunshine could be done in yellow or gold ink` which would contrast eti ctively with the black and white blizzard scene (3.

Again, if a given scene is done in yellow ink and is viewed through a transparent or semi-transparent sheet printed with a balli tone in blue, there is a blending of the colors to give a green effect.

Color may also be used for total or partial concealment. lt letters or a scene on a lower sheet is done, for example, in red ink and is viewed through a red screen. the letters or the scene become invisible, or nearly so. If the transparent sheet 8 were green and the lettering 17 done in green ink, such lettering would be practically invisible when viewed through sheet 8.

a picture 32 showing a business man work-v with lines 33 delineating a picture Frame.

The second sheet 34 shows the same business man resting and relaxing on a beach in Bermuda. On this second sheet` there is a beach 36 in one tone, such as yellow, and the sea 37 is another tone, such as blue, with a ship 38 and lettering 39.

When the top sheet is placed on the lollowing sheet the ligure 35 is concealed by the scene 32. The beach 36, preferably in one solid toile, when viewed through the top sheet, forms the floor 36a ol the olice; the sea 37, preferably in another solid tone, forms the wall 37a of the ofiiee; the ship 38 appears in place in the picture frame 33. That is to say, a symbol, such as the beach, lnay mean one thing when viewed alone, but may mean another thing (the floor of the room) when viewed through the transparent sheet. The lettering 39 also appears through thev transparent sheet. Then the reader sees the two sheets together, in Fig. 4, he sees the lettering 39 through the sheet and his curiosity is at once aroused as to what Bermuda has to do with a business;

man. He thereupon lifts the sheet and sees the same business man recupcrating from business cares on the sands of Bermuda.

Subsequent sheets could carry along the same idea by designating other scenes in Bermuda, by showing hotel rates, Steamship fares and the like.

The lettering 31, and in fact any other symbols on the top sheet, could be printed on an opaque panel 40. (.)n the reverse side 4l of the sheet, directly back of the. panel 40. symbols or indicia such as the lettering 42, are placed, so that both sides ol the sheet are utilized.

Figs. 7 and 8 illustrate an embodiment ot' the invention utilizing only a single transparent or semi-transparent sheet. This sheet, indicated at 50, is provided with an opaque panel 51 containing lettering 52 and the figure ot a man 53 looking atl bills, the impression created en the reader being that it is impossible for this man to buy a new car this year.

The reverse side ot this sheet, indicated at a, as shown in Fig. 8, shows the figure ot' the same man, the lines showing through from the obverse side of the sheet. Direct- 1y back of the opaque panel 51 is other lettering 55, pointing' out that by using a time payment system it is entirely possible to buy a new car this year.. This sheet shows a picture 54 of the car. Vhen the obverse ing in his ofiice under high pressure, and" side of the sheet is viewed as in Fig. 7, the car 54 is visibleon account of the transparency of the sheet.

The reader, in looking at the obverse side of the sheet, as in Fig. 7, gets a primary impression to the general effect that it would be impossible to buy a new car this year, but his curiosity is aroused by seeing the car 54 somewhat faintly from the other side of the sheet, and he is prompted to turn the sheet over, the result of which is that a supplementary impression is created to the effect that he will, by using a certain time payment plan, be able to buy a new car' in spite of bills and hard times.

Referring now to Figs. 9, 10 and 11, the first or top sheet is for the most part opaque, but is provided with a transparent or semi-transparent portion, indicated generally at 61. The second sheet 62 is preferably opaque for the most part, or has its transparency materially reduced, as by embossing, roughening or the like. This second sheet has a transparent window 63. The third sheet 64 shows a vacation scene 65.

Corning back to the first sheet, this sheet shows a worker dreaming of avacation in the Catskills. The transparent window 61 is provided with appropriate lines 66 indieating curtains for the window. The dream of the Worker is hazily outlined by the foggy line 67. The actual dream is the scene a., which is a portion of scene 65 from the last sheet 64. This Iscene shows through window 63 on the second sheet G2 and also shows through the Window on the sheet 60.

The second sheet 62 shows the same worker in a railway station on the way to a realization of the dream of Fig. 9. On the wall of the station ,is apparently a poster about the Catskills. However, the subject matter of the poster is formed by symbols or indicia 656 from the scene 65 on the third sheet 64.

In this embodiment, as wellas in Figs. 4, 5 and 6, symbols on one sheet mean one thing when read in connection with that sheet, but meansomething else when read yin connection with another sheet.k That is to say, the mountain scene of Fig. 12 represents an actual scene in the Catskills. In Fia. 11, the same scene is a part of a poster. In ig. 9, the 4same scene .is part of a dream. Since this scene has to show through the two transparent sheets 62 and 60, it will appear a little hazy or foggy, which is not linappropriate for a dream.

Color may be used to enhance the effectiveness of this embodiment of the invention. If the scene 65 on sheet 64 were done in green ink, the scene 65a could be rendered nearl invisible by making the transparent wincibw 61 green. Also, all of sheet 62 might be green, except the window 63, which would be clear and so most of scene 65 would be invisible. Also, a color blend effect is possible by making the transparent portion 63 yellow, suggestive of sunshine on the scene 6517.

The invention is usually carried out by using two or more sheets reading from left to right, as the ordinary book is read, for conveying a message or information, as has been fully described. However, these same sheets, by the use of opaque panels or other screening means, and by the use of appropriate symbols or indicia placed or printed on the reverse sides of these sheets, could be used for conveying anbther message or other information, the reverse sides of these sheets being read from right to left, as will readily be understood.

In another aspect of the invention, the two sheets may be viewed in either order and still the desired effect obtained. For example, the first sheet would be transparent and would show curtains for a window. The second or following sheet would show the bare, uncul'tained window. l/Vhen the two sheets are together, the curtains would appear in place on the window. If the curtained window is seen first, and then the bare window, or vice versa, the same effective contrast is obtained. As a corollary to this, -the sheets, two or more, may be assembled so that they are readable only one way, that is, with the opaque sheet first and the transparent `sheet second, the reverse of the normal order. The reader first views the opaque sheet and then places on it the transparent sheet from' the right and views the two together.

The term to screen as used in the claims is intended to mean to render less clearly visible, to hide, or to tone down.

The term transparent as used in the specification is intended to be of some breadth, meaning transmitting rays of light, so that objects or pictures or lettering, etc., can be seen with more or less definiteness; the term semi-transparent7 is intended to mean transparent to a less degree than the sheets referred to as transparent and meaning more particularly transmitting light so that bodies or pictures, etc., may be vaguely or indistinctly seen through the sheet or medium. The term transparent as used in the claims is intended to cover both transparent and semi-transparent as above defined. It is intended to cover a sheet the transparency of which may have been reduced by printing various symbols or indicia thereon, or by the use of embossing on the paper, or by the use of opaque panels or backgrounds or the like. Moreover, a sheet need not be transparent throughout its entire 'extent but one or more portions of it may be rendered transparent either before or after the symbols are placed on it in any suitable way. The sheet could be for the most partlopuqnefparts Abei11gfparent -sheet is where there is a heading or rendered transparent'fn--any suitable` way to lprovide Vone-onmore transparent panels. r a g lhe term transparent 1s intended to cover v"these variations.

The transparency of the sheet can also if. desired be reduced by embossing or otherwise altering or roughening the surface of the sheet, so that symbols or indicia, when viewed through it, are given a somewhat hazy or foggy efl'ect, which serves to arouse the curiosity of the reader and prompts him to lift the transparent sheet and see what is below it.

It will be 'obvious to those skilled in the art that the present invention is not limited to the specific embodiments disclosed, nor to sheets arran ed in book or pamphlet form, but is applicale to any arrangement for displaying advertisements or the like or conveying any sort of information in a str1king and novel manner. Lights may be used, as is understood in this art, on either or both sides of the sheetor sheets for aiding the visibility of the indica through the transparent sheet.

The invention may be embodied, for eX- ample, in advertising booklets, life insurance circulars, booklets relating to cleansing preparations, paints, cosmetics, etc., travel circulars, Christmas cards, merchandise wrappers, educational or amusement devices etc.

The screening or concealment of the symbols on the second surface or sheet may vary in degree; that is to say, such symbols may be entirely obscured, or they may be partially hidden or toned down so that they are partially obscured.

This invention presents many advantages over what are known as cut-outs, where a top sheetis provided with holes cut through it. From the mechanical point of view, the cut-out is much more diflicult and expensive,

because dies have to be very accurately made so that the cut-out will accurately register with other matter. If the cut-outs are made by hand, this is slow, tedious, and expensive.

All this die cutting and die press work is eliminated with this invention, becauser no cut-outs are used, andthe article can be -madev in a print shop by feeding through 'small picture on the first sheet and 1t is ...desirable to have practically the entire second sheet visible. This is notlpossible with cut-outs.

The terms symbols or indicia las used in the claims, are intended to cover any appropriate discriminating marks, indications or appearances, such as designs, panels, pictures, diagrams, words, numbers, scenery, human or other figures, etc., alone or in combination which are visible on or through a surface or sheet.
